Components re-rendering multiple times when they ony need to render once

[Zander1983]

Description

Directly under function Plot() { add console.log("props.plotIndex is ", props.plotIndex);
Go to an experiment with 3 files - you should see:

props.plotIndex is  0-0
props.plotIndex is  1-0
props.plotIndex is  2-0

instead you see:

props.plotIndex is 0-0
props.plotIndex is 1-0
props.plotIndex is 2-0
props.plotIndex is 0-0
props.plotIndex is 1-0
props.plotIndex is 2-0
props.plotIndex is 0-0
props.plotIndex is 1-0
props.plotIndex is 2-0
props.plotIndex is 0-0
props.plotIndex is 1-0
props.plotIndex is 2-0
props.plotIndex is 0-0
props.plotIndex is 1-0
props.plotIndex is 2-0
